摘要：

An eight-step synthesis of 11,12-didehydrodibenzo[a,e]cycloocten-5(6H)-one (10) was developed. The structure of 10 was assigned by spectroscopic means and confirmed by X-ray analysis of its 2,4-dinitrophenylhydrazone derivative. Reaction of the triple bond of 10 with dicarbonyl(eta(5)-cyclopentadienyl)cobalt or dicarbonyl(eta(5)-pentamethylcyclopentadienyl)cobalt gave the corresponding metal-stabilized cyclobutadiene complexes.
